BUILDING-BLOCK.

Specification of letters Patent.

Patented a HR: in-1910.

Application filed June 2, 1909. Serial No. 499,773.

To all whom it may concern:

Be it known that I, VVARWIOK G. BATE, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Building- Blocks, ofwhich the following is a specification, reference being had therein tothe accompanying drawin This invention re ates to walls of buildings,and especially to that class of building walls which are formed ofhollow building blocks.

y The invention has for its object to pro vide an improved wall forbuildings formed of hollow building blocks so constructed and arrangedas to afford sufiicient protection against heat and cold.

Figure .1 is a perspective view of a portion of a wall constructed inaccordance with this invention. Fig. 2 is a perspective view of. a blockadapted for corners or angles. Fig, 3 is a similar view of a blockadapted for circular work. Fig. i "is a 25 transverse sectionalviewtakenon the line 44, Fig. 3.

Referrlng to said drawin s by numerals,

and more particularlyto Fig. 1 thereof, it.

will be observed that the blocks forming the wall shown in said figureare of two sizes, the lower blocks l-b'eing especially adapted forfoundation work and the smaller blocks which are mounted thereon anddesignated by the numeral 2 are adapted for upper courses.

The blocks in all forms shown in the ac-' companying drawings embody thesame idea and arrangement of air spaces or chambers, and hence it willbe understood that the showing of the rectangular blocks, the angularblocks, and the semi-circular blocks is to illustrate the generalapplication of the invention to blocks of various shapes. Said blocksare composed of the side Walls 3, end walls 4.- and transverselyextending connecting partition 44 which centrally divides the blocksinto two open chambers 5 and 6. The side walls 3' are provided with twoor more alined vertical openings or slots 7 and the end walls areprovided with a similar openin .8, and each corner of the blocks areprovi ed withthe angle openings or slots 9,

all of said slots extending entirely through the block. The blocksmayalo provided 1 with scoring arranged at their ends and sides, aslndicated at 10 in Fig. 1, to facilitate the separating of theblockswhen necessary or desirable. Some of the blocks, for instance therectangular ones shown in Fig. 1 may have their transverse partitions 4:proyided with a vertically extending opening 11. a

In assembling the blocks to build a wall or other structure, the blocksmay be ar ranged as suggested in Fig. 1, themortar 12 (indicated bybroken lines in Fig I) placed over the vertical openings of the block sothat when the blocks are superimposed, some of the mortar will be forcedinto said openings, as indicated in Fig. 4, thereby sealing theopenings, leaving air chambers in each wall of the blocks the heat andcold insulating advantages of which will be apparent.

It will be seen from. the foregoing that with the use of blocksconstructed in accordance with this invention, hollow walls may beformed, which are composed of a lurality of blocks, each hav ng indepenent air chambers, said air chambers also forming the means whereby theblocks are securely held together owing to the interlocking engagementof the mortar therewith. The blocks are also preferably provided withend grooves 13 which serve to receive the mortar used between theabuttingends of I the blocks.

What I claim as my invention is A wall for buildings formed of buildingblocks, each made in one piece and provided with a plurality of openchambers, the side and end walls of said blocks having a series ofelongated narrow vertical spaces located at intervals in said wall, andextending en-' tirely through the walls from the top to the bottomthereof, and between the sides of said walls, and mortar spread betweenthe adjacent tops and bottoms of said blocks and partly entering intosaid elongated narrow vertical spaces and binding said blocks to gether,and forming sealed air chambers in said blocks.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
